Overview
This is a polyclonal anti-IgG antibody raised in Guinea pig, with confirmed utility in ELISA, WB. Designed to detect IgG in Goat, supporting researchers in others contexts.
Key elements and design rationale
- Immunogen: Goat IgG heavy chain (Native Protein) — determines the epitope region recognized; confirm epitope compatibility with your sample preparation and expected PTMs.
- Host (Guinea pig): Requires anti-guinea pig-IgG secondary reagents. Mismatched secondaries result in no signal. Consider host species when multiplexing.
- Polyclonal: Recognizes multiple epitopes — robust signal across varied preparations, with inherent lot-to-lot variability. Isotype controls and lot qualification recommended.
- Isotype (IgG): Secondary antibodies and isotype controls must match IgG from Guinea pig. Relevant for multiplexing and Protein A/G compatibility.
- Purification (Protein G purification): Reduces non-specific immunoglobulin populations, improving signal-to-noise in quantitative immunoassay formats.
Biological background
IgG (also known as IgG) is a protein studied in Goat systems. Expression levels, subcellular localization, and post-translational modifications vary across cell types, tissues, and disease states — factors that influence antibody-based detection outcomes. Researchers are encouraged to consult UniProt, NCBI Gene, and primary literature for current annotation of IgG biology relevant to others.
Common research applications
- ELISA: Sandwich or indirect ELISA quantifies soluble/secreted target in biological fluids or cell culture supernatants.
- WB: Western blot confirms target MW and detects isoforms/fragments under denaturing conditions.
Notes for experimental interpretation
- Isotype controls: Include IgG from Guinea pig at equivalent concentration to assess non-specific background.
- Cross-reactivity/isoforms: Polyclonal preparations may cross-react with related proteins or isoforms — validate with siRNA KD, KO lysate, or recombinant protein controls.
- Matrix effects: Sample matrix (serum, plasma, lysate, homogenate) may influence performance; pilot dilution linearity and spike-recovery experiments before full quantitative studies.
- Species reactivity: Confirmed for Goat; extrapolation to untested species requires empirical validation.
This product is a polyclonal antibody purified from guinea pig antiserum.
IgG is a protein target in Goat biology. This polyclonal antibody raised in Guinea pig detects IgG and is validated for ELISA, WB applications.
This antibody is reported reactive against Goat. Immunogen derived from Goat. Cross-reactivity with unlisted species should not be assumed — contact us or consult the datasheet for homology data.
Supplier reports performance in ELISA, WB. Dilution optimization, blocking, and appropriate controls are required per format. Contact BioHippo for recommended working concentrations.
This non-conjugated (IgG) antibody requires a secondary anti-guinea pig IgG conjugated to HRP, AP, fluorophore, or biotin. Match the secondary to the host (Guinea pig) and isotype (IgG).
(1) Isotype control — IgG from Guinea pig at matching concentration; (2) Positive control — lysate/cell line expressing IgG; (3) Negative control — siRNA KD or KO sample to confirm specificity; (4) Dilution linearity — verify proportional signal decrease for quantitative applications.
